NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed. June 25, 1908. Serial No. 440,378.

useful Improvements in Non-Refillable Bot-v tles, of which the followingis a specification. This lnvention contemplates certain new and usefulimprovements 1n non-refillable bottles, and the object of the inventionis an improved vessel of this character that embodies a peculiar valvemechanism which in nowise interferes with the ready egress of the liquidfrom the bottle, but which effectually prevents refilling of the bottleafterlit has become emptied or partially emptied, thereby protecting themanufacturers of certain liquids, since it eliminates the fraudulentpractice of refilling the bottle with a cheaper grade of liquid andplacing it upon the market as an original package under the name ordistinctive mark of the former manufacturer.

With this and other objects in view that will more fully appear as thedescription proceeds, the invention consists in certain constructionsand arrangements of the parts that I shall hereinafter fully describe,and then point out the novel features thereof in the appended claim.

For a full understanding of the invention and the merits thereof, and toacquire a )7 knowledge of the details of construction, reference is tobe had to the following description and accompanying drawing, in which:

Figure l is a vertical section of a non-refillable bottle constructed inaccordance with my invention; Fig. 2 is a horizontal section on the linea2m of Fig. 1.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

My improved non-refillable bottle embodies a body portion 1 which may beof any desired construction or design, and a neck 2 that communicateswith the body portion and that is formed intermediate of its ends withan enlarged or distended portion 3 provided at its lower end with avalve seat 4. This valve seat is designed to be controlled by a ballvalve 5 which may be of any desired material, of less specific gravitythan the liquid filling the bottle. This ball valve is mounted within acylindrical valve chamber or cage 6 that, in the present instance, is

formed of glass and that extends vertically upwardly from the valve seatl in spaced relation to the neck, as shown, the internal diameter ofthis valve chamber being substantially equal to the diameter of the ballvalve, so as to permit the vertical movement of the latter, but preventany rolling thereof from side to side. The lower portion of the wall ofthe valve chamber is solid, while the upper portion is longitudinallyslitted, as indicated at 7, so as to establish communication between thevalve chamber and the interior of the neck. The neck 2 is provided,contiguous to the upper end of the valve chamber, with a transversepartition or baffle plate 8 having upper and lower concaved faces,communication being established between the portions of the neck onopposite sides of the baffle plate by means of a series of downwardlydiverging openings 9 leading from the space between the cage and theenlarged portion 3, as shown.

The arrangement of the openings 9 effectually prevents the successfulintroduction of a wire or similar tool into the neck to tamper with thevalve element and hold the ball valve from its seat. By having the lowerportion of the wall of the valve chamber solid, as previously described,a wire or the like inserted through one of the openings 9 and followingthe line of the neck of the bottle, is prevented from reaching the ballvalve to fraudulently manipulate the latter.

In the practical use of my improved nonrefillable bottle, the ball valvenormally rests upon the valve seat 4 to close the same when the bottleis in an upright position, and in order to obtain the contents of thebottle, it is necessary to completely invert the latter so that the ballvalve will fall from its seat and permit the liquid to pass therethroughinto the valve chamber, through the slits 7 in the latter, and thenthrough the openings 9 into the mouth of the bottle from which it isdischarged into the desired vessel.

As the ball valve normally rests upon its seat when the bottle is in anupright position, any attempt to refill the bottle will obviously beunsuccessful, since the weightof the liquid introduced into the neck 2will only serve to further hold the ball valve in an operative position.Any attempt to refill the bottle when the latter is upon its side orinverted or in any intermediate position, will be frustrated, since asthe valve is of less specific gravity than the liquid which the bottleis used to package, it Wlll be carried agalnst 1ts valve seat by thelncomlng liquid, and siphoning or pressure will only serve to moreforcibly maintain it in position.

From the above description, in connection with the accompanying drawing,it will be apparent that I have provided a simple, durable and efficientconstruction of nonrefillable bottle that is controlled by an improvedvalve mechanism, the parts of which may be all formed of glass and blownintegral with the neck of the bottle, or otherwise suitably securedtherein, and that is positive in action so as to effectually prevent theintroduction of any liquid into the bottle, after the same has beenemptied.

Having thus described the invention, what I claim is:

A bottle having a bulbous neck, the side walls of which are contractedat their juncture with the body of the neck to form a valve seat, a ballvalve engaging said seat, an integral partition extending across thecenter of the neck of the bottle and defining superposed compartments,one of which is unobstructed and provided with inclined interior wallsconverging in the direction of the mouth of the neck, and the othercompartment having its interior walls converging in the direction of thevalve seat and provided with an integral tubular member extendingvertically from the valve seat to the lower face of the partition andforming a continuation of the side walls of said valve seat, saidtubular member being imperforate at the valve seat and provided abovesaid valve seat with spaced vertical slot-s communicating with the lowercompartment, there being a depression formed in the lower face of thepartition at said tubular member for the reception of the valve when thebottle is inverted, the upper and lower faces of the partition beingconcave and imperforate at the center thereof and provided with aplurality of inclined discharge passages on each side of the imperforateportion, said passages forming a source of co1nmunication between theupper and lower compartments and converging in the direc tion of themouth of the neck.

In testimony whereof I affix my signature in presence of two witnesses.
